Abstract

A sliding door installation includes a roller running track and at least one roller carriage supported to be displaceable in the roller running track, at which carriage a sliding door is attached. A closing device is provided with an elastic traction means, wherein a first end of the elastic traction means is stationarily attached with regard to the roller running track, and a second end of the elastic traction means is attached to the at least one roller carriage for changing the tensile stress in the elastic traction means during a movement of the roller carriage in the roller running track.

First claim

The invention claimed is:

1. A sliding door installation, including a roller running track and at least one roller carriage supported to be displaceable in the roller running track, at which carriage a sliding door is attached, wherein a closing device is provided with an elastic traction means, wherein a first end of the elastic traction means is stationarily attached with regard to the roller running track, and a second end of the elastic traction means is attached to the at least one roller carriage for changing a tensile stress in the elastic traction means during a movement of the roller carriage in the roller running track, wherein the first end of the elastic traction means is attached with a first knot stationarily with regard to the roller running track or the second end of the elastic traction means is attached with a second knot to the at least one roller carriage, wherein the elastic traction means includes a monofile woven wrapping configured to loosen the knot.

2. The sliding door installation according to claim 1 , wherein the closing device includes at least one redirection means, around which the elastic traction means is guided between the first end and the second end for a lengthening of a geometrical extension of the elastic traction means.

3. The sliding door installation according to claim 1 , wherein the closing device or the elastic traction means meets at least one of the following parameters:
maximum tensile stress with the sliding door being opened between 20 N and 35 N,
maximum tensile stress with the sliding door being closed between 10 N and 25 N,
difference between tensile stress with the sliding door being opened and tensile stress with the sliding door being closed between 5 N and 25 N,
length of the elastic traction means in a neutral fiber between 4 m and 5 m in a mounting condition, and
exterior diameter of the elastic traction means being 5 mm to 8 mm.

4. The sliding door installation according to claim 1 , wherein the first end of the elastic traction means is attached with a first knot to the at least one roller carriage or the second end of the elastic traction means is attached with a second knot stationarily with regard to the roller running track.

5. The sliding door installation according to claim 1 , wherein a dampening device is provided for dampening the movement of the roller carriage exclusively into a first terminal position, which corresponds to a closed position of the sliding door.

6. The sliding door installation according to claim 1 , wherein a latching device is provided with a mobile latching element, which is disposed at the roller carriage, and with a stationary fixing element in relation to the roller running track for a reversible latching cooperation with the mobile latching element in the roller carriage in a second terminal position, which corresponds to an opened position of the sliding door.

7. The sliding door installation according to claim 6 , wherein the latching device includes a trigger function for cancelling the latching cooperation between the latching element and the fixing element during a movement of the roller carriage beyond the second terminal position.

8. The sliding door installation according to claim 1 , wherein the elastic traction means includes at least one of the following embodiments:
a woven rubber cord,
a silicone round cord, and
a silicone tube.

9. The sliding door installation according to claim 1 , wherein the elastic traction means has tensile stress characteristics with a difference of the tensile stress in the elastic traction means between a first terminal position of the roller carriage, which corresponds to a closed position of the sliding door, and a second terminal position of the roller carriage, which corresponds to an opened position of the sliding door, wherein the difference is designed between 50% and 200% of the pretension of elastic traction means in the first terminal position of the roller carriage.

10. The sliding door installation according to claim 1 , wherein a length of the elastic traction means between the first end and the second end in a pretensioned condition is designed in the range between 200% and 500% of the distance of a first terminal position of the roller carriage, which corresponds to a closed position of the sliding door, and a second terminal position of the roller carriage, which corresponds to an opened position of the sliding door.

11. A method for mounting a sliding door installation having the features of claim 1 , including the following steps:
inserting the roller carriage with a sliding door attached to the roller carriage, into the roller running track,
connecting the first end of the elastic traction means to a point, which is stationary with regard to the roller running track,
connecting the second end of the elastic traction means to the roller carriage while introducing the tensile stress as a pretension into the elastic traction means.
